The Plantronics M55 Bluetooth headset lets you do more with your voice - answer calls without pressing buttons or use the Vocalyst service to manage emails. DeepSleep mode lets the M55 stay charged for up to five months, so it’s ready when you want to hear music, Internet radio, or simply take a call.

Keep your hands free during phone calls, whether you're organizing paperwork for your next meeting or wrangling the kids into the car. This Bluetooth headset features noise, wind and echo reduction, so you can hear and speak clearly from just about anywhere.

Sound quality is good, and people I've talked to say I sound clear and there's no background noise.

I bought one of these for my wife a few months ago and she liked it. The price was right and it seemed to work well for noise cancellation.

Decent noise cancelling, as I've used it several times with the windows cracked down in my jeep and people can still hear me fine.

I picked this up to use up at here at work. Unfortunately, the noise filtering was unacceptable, as was the volume.

I have been told that the person on the other end can hear a lot of background noise. If your in a quiet house while talking then it seems ok, but if there is any noise whatsoever the other person will be able to hear it loudly.

The audio is crisp and clear, and I'm told from people I've conversed with that the noise-reduction is so good they don't even notice I'm using a headset.

I'm constantly listening to podcasts and audiobooks through this headset everyday at work, during which it consistently gives about 10+ hours of battery life, more than enough time to include the work shift and the commutes to and from.

Great bluetooth!!! The noise cancelation is amazing, even helps against wind!!!

The noise cancellation isn't as good as my old Jawbone - doesn't seem to minimize noise from windy conditions at all. For the price, it is very good - fit and comfort are terrific.

Good talk time; works well. Clear for both listening and to the other side with noise cancelling.

Talk time, battery level, and other alerts available in English, French or Spanish, Music and streaming audio can be controlled from the headset, Onscreen headset battery meter available for both iPhone and Android

Sound is great! Despite the slightly uncomfortable fit, and the uselsss hands-free answering feature, it is still a good product for the money.

M55 has some neat features like the deep sleep mode (because what good would the locator app be, if it's dead somewhere??), but I haven't had a chance to use that yet.

Nice feature that tells you how much battery life is left, which I think is a very nice to have.

Another nice feature , when you turn it on it tells you remaining talk time and what phone. It pairs effortlessly with my GS5, I had big problems with that with my last ABCO headset.

Also, the deep sleep feature is a ingenious idea as well. The fact that it is light weight is cool.

As for features we all know we aren't supposed to text and drive but recently I went on a three hour road trip. When you have this device on and you hear the tone for your text messages, you can ask it to "Read me my text message" and it will and then ask you if you want to reply.

The unit fits into my small ear perfectly ( I had to buy an additional insert cover smaller size). The insert that is sold with a blue tooth is size medium.

Music/podcasts/etc are paused by pushing the adjacent volume up & volume down buttons simultaneously then resumed with the same maneuver. Both buttons are quite 'clicky' offering plenty of positive feedback--pressing both is easy with one finger or thumb depending on right or left ear usage.

But my favorite parts of this are the media capability and battery life: The headset includes easy buttons for volume and media playback controls

Long-pressing the big button does activate your phone's voice-control mode, which is good.

Battery charged quicky, it was the easiest to setup out of the box. Turned it on, it knew it was never paired so looked for my phone, paired and done.

11 talk time is luxurious I go days without having to charge and it fits a standard microUSB car charger

Love this headset. Great reception and it charges fast. I really like that it allows you to talk for up to 11 hours before needing a charge.

When fully charged, it claims to have a talk time of 11 hours. perhaps this means at minimum volume, as i have found the actual time to be between 20-30% - i.e., perhaps up to 4 hours.

It charges quickly and no one ever complains about being able to hear me. Best of all, it works with the various apps, including music on my phone. Buy it!!

Battery life is unbeatable and easily goes all day at work and then some streaming Mets baseball while fishing!!

It charges fast and I've never had any connection issues between the phone and the device.

It easily pairs with my phone, charges quickly, and lasts a long time.

Battery life is great. It tells you it has 11 hours when it's fully charged, but after using it for a full 8-9 hour work day off and on, it usually tells me I have 5-6 hours remaining. It'll definitely last a long time.

I liked this Bluetooth but it will no longer hold a charge I have only had it 4 months this is Ridiculous. disgusted!!!!!
